A method and system for obtaining a routing table in a data center

Abstract

The present invention proposes a method and system for obtaining a routing table in a data center. The method includes the steps of obtaining an OSPF network routing table, obtaining a Router LSA and a Network LSA, calculating an intra-domain route of the OSPF network according to the Router LSA and Network LSA, and obtaining a Summary LSA, And calculate the route between the regional routes, obtain AS External LSA, calculate the external route of the autonomous domain; obtain the ISIS network routing table step, obtain the data table Link_state_main and data table Link_state_attach, query the device name of all routing devices in Link_state_main, use the device name as the id and Insert the graph database Neo4j to obtain all routing devices, establish link relationships for all routing devices, obtain LSPs generated by all pseudo-nodes, traverse the LSPs generated by pseudo-nodes of all routing devices, and insert the connection relationship between all routing devices into the graph database Neo4j, and add a distance value metric for the connection relationship, and obtain the routing table according to the collection generated by all router devices.

Description

technical field [0001] The invention relates to the technical field of computer network interconnection communication, in particular to a method and system for obtaining a routing table in a data center. Background technique [0002] With the development of cloud computing and big data, the construction of IDC data centers has ushered in a construction climax. As the cost of data centers continues to soar, the focus of data center management has begun to shift to network operation and maintenance and network optimization. In the process, the routing table has become a very important basic data. With the routing table data, the path from any node to the destination node can be grasped, thus laying the foundation for traffic engineering, network optimization and network modeling. [0003] The existing routing table acquisition methods are roughly divided into three types: log in to the router CLI to collect, provide by the manufacturer, and collect from the network. Logging i...

Problems solved by technology

Logging in to the router to view often requires manual assistance. Due to the large number of routers in the data center and the different routing table formats of routers from different manufacturers, this method is less feasible to obtain the routing table; manufacturers often need to configure dedicated routers to provide external output routing tables Interface, the routing table obtained by this method is more accurate, but the price is relatively expensive, and the routing table data of non-dedicated routers cannot be collected; the network collection mainly uses the flood link state information in the network and uses the SPF algorithm to calculate the route. High cost performance, providing more accurate restoration routing table, and high real-time performance
